GEORGE W. KNAPP, JR., OF BALTIMORE, MARYLAND, ASSIGNOR TO NATIONAL ENAM-ELING- AND STAMPING COMPANY, OF BALTIMORE, MARYLAND, A CORPORATION OFNEW JERSEY.

BUG AND FLY TRAP.

To all whom it may concern Be it known that I, GEORGE W. KNAPP, Jr., acitizen of the United States, residing at Baltimore, in the State ofMaryland, have invented certain new and useful Improvements in Eng andFly Traps, of which the following is a specification.

This invention relates to certain improve ments in bait pans for bug andfly traps, the trap being 01": the type that has an inner wire gauzedome with a top-opening that communicates with an outer dome.

The object of this invention is to provide a sheet-metal base or baitpanwhose bottom has a surrounding up-standing wall, and bridges thatincline downwardly and outwardly from said wall and connect with anannular downwardly-inclined flange that is lower than the top-edge ofsaid wall, and said parts forming entrance-slots which are lower thansaid top-edge, whereby the said wall conceals the slots from the view offlies or insects that are inside and resting on the bottom of thebase-pan.

The accompanying drawing illustrates the invention wherein,

Figure 1, shows a side elevation of the assembled trap. Fig. 2,illustrates a vertical sectional elevation of the same. Fig. 3, shows atop plan view of the bait pan. Fig. 4, illustrates an enlarged sectionaldetail of the pan and a downwardly inclined bridge that connects withthe annular flange, and also shows the lower circular edges of the twotrap domes about to be seated on the flange,the section being taken onthe line 44 of Fig. 3. Fig. 5, is another sectional detail showing thedomes seated on the annular flange, the section be ing on line 5-5.

In the drawing the numeral, 1, designates the bait-pan which has a flatbottom portion, 2; an annular convex head, 3, and an upstanding wall, 4,which encircles the bottom of the pan and project therefrom verticallyupward.

The Vertical wall, 4, at its top has radial bridges, 6, see Fig. 4, thatsustain a downwardly inclined flange, 5, which latter has positionVertically considered in a plane between the top edge, 8, of the saidvertical wall, 4, and the flat portion of the bottom. It will thus benoted that the annular Specification of Letters Patent.

downwardly-inclined flange, 5, depends from the top edge, 8, of theupstanding pan wall, 4.

Between the downwardly-inclined bridges is a series of entrance slots,7, which latter have concentric edges, 8, and, 9, respectively whichedges have position in diflerenthorizontal planes,the outermostconcentric edge, 9, being in a plane lower than the innermost edge, 8,which latter is the top edge of the vertical flange, 4.

An annular retaining wall, 10, is provided around the inclinedsupporting flange, 5, and extends upwardly therefrom. This wall, 10,also flares slightly as it extends away from the flange, 5, and itsupper edge has an annular bead, 11, for a purpose presently to bedescribed.

The cage part of the trap comprises two foraminous domes, 12, and, 13,respectively formed, in the present instance of wire. The inner dome,12, has a circular lower edge which is bound by a sheet metal band, 14,which forms a circular hem and from said band the dome arches or curvesover the center of the pan and is provided with an opening, 15, at thetop. The outer dome, 13, is also provided with a band, 16, around itslower circular edge which is just enough larger than the band, 14, onthe inner dome to snugly receive or take around the latter band. Thisouter dome entirely covers the inner dome and the lower bound edges ofthe two domes are of such diameter that they may be easily forced downpast the head, 11, on the wall, 10, of the supporting flange,'5, and beseated on the said inclined supporting flange between the lower slotedge, 9, and the higher rim-edge, 8, as shown in Figs. 2 and 5.

In practice the bait will be placed on the central flat base portion, 2,where it is confined by the annular convex bead, 3, and prevented fromspreading to the vertical rim flange, 4, where it would be troublesometo clean. The flies or insects must pass up through the segment entranceslots, 7, and then over the high edge, 8, of the pan then downward toreach the bait, which is deposited in the center of the pan base. Whenthe flies are on the base however, the slots, 7, which are below the rimedge, 8, are concealed from the flies by the top of the interposedupstanding Wall, 4-, and the only opening to the light which the fly orinsect can see is the opening, 15, in the top of the inner dome, andtherefore escape is sought through that opening with the result that thefly or insect is efliectually trapped.

Some bug and fly traps have the slots through which the insect enters sopositioned that it is quite easy for the insect, after it has enteredthrough the slot to the base-pan, to return and escape by the slots, butmy improved construct-ion tends to conceal the slots to the view of theinsect after it has passed in to the pan, and rendersv sustained on theannular wall below and 30 encircling the outer edges of all thesegmental slots.

In testimony whereof I affix my signature in presence of two witnesses.
